On the former Freeform drama, Harding played school teacher Ezra Fitz, who fell in love with his student Aria (Lucy Hale). After a very tumultuous relationship, the couple ended the series with a wedding.

Meanwhile, DeVitto played Melissa Hastings — Spencer's (Troian Bellisario) older sister — who was believed to be the ominous "A" until it was discovered that (Spoiler!) it was actually Spencer's long-lost twin sister.

We hope Harding's character doesn't interfere with DeVitto's onscreen wedding to co-star Nick Gehlfuss (Dr. Will Halstead). The two have been planning the big day for the last few episodes, but we have a feeling it may not be a smooth celebration.
